Value from my work will be extracted because the sales staff needs to be paid, and the accountants need to be paid, and management, and everyone I rely on as a worker to both do my job and get paid.
Profit is not wages paid to workers other than yourself, even workers performing other job functions. Other workers receive wages because they provide labor, just as you receive wages because you provide labor. Profit is value generated by your labor, and by the labor of other workers, that is appropriated by the owners of a business, claimed for themselves, despite their not having contributed any labor to the productive processes of generating the wealth.
All sophisticated productive systems are based on division of labor, and even most primitive ones entail at least some. Division of labor is as old as the hills, but the unbounded accumulation of private wealth by the labor of workers is not universal and indeed relatively recent.
You should not support the profit motive of your employer simply because you have an occupational specialization. One is not bound to the other.
There will always be something additional removed for profit above and beyond the cost of all of those other labor needs that make my job possible, since I’m not the only person contributing to the earnings of the company, and the only way to make what I’m worth is to get out on my own,
Along a similar theme as above, you are conflating organization of labor in general, with particularly labor being organized by a private business under the profit motive.
The value I’m seeking to be recognised for is that I’m worth paying a higher percentage of the earnings I’m capable of bringing in.
Employers always pay workers, with the rarest exceptions, the absolute minimum required to retain their labor.
Otherwise, they would be eliminated by businesses that were more competitive.
